A novel approach for energy analysis called the "Bridge Method" is being developed in this research program. If the Bridge Method is fully-developed and transferred to industry, it will represent a breakthrough that better enables energy analysis and energy use reduction in industrial processes using a method that is more effective than traditional techniques such as pinch analysis, and the significant GHG reductions associated with this. The Bridge Method considers the Energy Transfer Diagram (ETD), which is a representation of energy transfer in industrial processes based on the first two laws of thermodynamics. The ETD presents how energy is conserved, and at the same time degraded across industrial process units. The ETD makes it possible to visualize all opportunities for increasing plant energy efficiency by modifications of the process operations, the heat-exchanger network (HEN), and the heat and power production system.***The overall objective of this research program is to continue to explore the fundamental aspects of the Bridge Method, ideally to the point where a global methodology can be developed that is suitable for application in industry. Four research themes will be addressed in this program including (a) the development of an optimization algorithm for the retrofit of heat exchange networks to reduce energy consumption by HEN retrofit, (b) the development of thermodynamic relationships for analyzing site-wide heat and power systems, (c) the development of a method for total site analysis for industrial clusters and especially for the case of biorefinery implementation in existing pulp and paper mills, and (d) assembling these tools into an overall methodology for the design of highly energy-efficient processes. The overall method should be user-friendly to process engineers working in the industrial environment. The originality of the Bridge Method lies with a better fundamental understanding and representation of energy conversion and degradation in industrial processes, and the incorporation of this understanding in a practical methodology for the design of energy efficient industrial processes. **

本研究计划正在开发一种新的能量分析方法，称为“桥梁方法”。如果桥梁方法得到充分发展并转移到工业中，它将代表一种突破，可以更好地实现能源分析和工业过程中的能源使用减少，使用比夹点分析等传统技术更有效的方法，并显着减少与此相关的温室气体。 桥法考虑能量传递图（ETD），它是基于热力学前两定律的工业过程中能量传递的表示。 ETD展示了如何在工业过程单元中节约能源，同时降低能源消耗。 通过ETD，您可以直观地看到通过修改工艺操作、热交换网络（HEN）和热电生产系统来提高工厂能效的所有机会。*该研究计划的总体目标是继续探索桥梁方法的基本方面，理想情况下，可以开发适合工业应用的全球方法。 四个研究主题将在该计划中解决，包括（a）开发一个优化算法的改造换热网络，以减少能源消耗的HEN改造，（B）的热力学关系的发展，用于分析整个站点的热和电力系统，（c）第（1）款开发一种方法，用于工业集群的总体现场分析，特别是在现有纸浆中实施生物精炼的情况下，米尔斯，以及（d）将这些工具组合成设计高能效工艺的总体方法。 整个方法对于在工业环境中工作的过程工程师来说应该是用户友好的。 桥方法的独创性在于对工业过程中的能量转换和降解有更好的基本理解和表示，并将这种理解纳入节能工业过程设计的实用方法中。**
